A road hog got instant justice after cutting up a tractor – finding himself sprayed with gallons of liquidised pig poo from the slurry tank it was towing.

The driver had tried to overtake on a roundabout but his red Vauxhall Astra clipped the back of the tank, opening the sewage outlet straight into his car.

It was then dragged several metres by the trailer, which continued to fill the car with its stinking cargo.
